- on the object's page, 'unpublish' the co-creator. In this way, the default (unmodified) object will still be available for purchase, and external links (like Google!) will continue to work.

- you can set the object to 'private'. In this way, it will be completely removed from the Shapeways website during your vacation. External links will break, and I guess I don't have to tell you that's bad for business.

There's no switch that does this for all models at once, onfortunately. I'll suggest that to our website developers.
